Design/Build is a construction project delivery system that helps us manage our project team from start to finish. The Design/Build system offers transparency for architects, engineers, and consultants. The result is substantial time savings for the owner. The Construction Manager/General Contractor (CM/GC) augments the General Contractor's traditional work scope with that of a Construction Manager. Under a single contract with the Owner early in the design phase, the CM/GC allows the General Contractor to collaborate with the Architect and Engineer on design development and preparation of design documents prior to finalizing budgets and beginning construction.

Colas Construction manages Pre-Construction services to support financial goals and schedules. Our standard approach involves working on design-development as the project progresses from the early stages throughout completion. Colas Construction has extensive building experience across public, private, and nonprofit sectors, and numerous factors make us the best choice for your next construction project. Our in-house structural concrete offers a unique advantage to our Clients to regulate pricing, enhance quality control, safety, and reduce scheduling impacts.
